I receive warnings() that make debugging difficult. I have two questions:
1. In this part of my script, I want my script to return “Inf”. I receive the following warning. In min(df12.[df12.[, 7] <= 0, 1]) : no non-missing arguments to min; returning Inf Is there are command to eliminate the warning message? 2. I use the following legend that returns a plot that I am happy with and no errors: legend("topright", title = "", legend = c( expression("Predictions:"), bquote(bar(u)[A] == .(u.a)), bquote(bar(u)[D] == .(u.d)) ), cex = c(0.75,0.75,0.75) ) At the same time, I receive the following warnings: warnings() Warning messages: 1: In if (xc < 0) text.width <- -text.width : the condition has length > 1 and only the first element will be used 2: In strheight(legend, units = "user", cex = cex)/yc : longer object length is not a multiple of shorter object length 3: In w0 * rep.int(0:(ncol - 1), rep.int(n.legpercol, ncol)) : longer object length is not a multiple of shorter object length 4: In left + xchar + xextra + (w0 * rep.int(0:(ncol - 1), ... : longer object length is not a multiple of shorter object length 5: In (rep.int(1L:n.legpercol, ncol)[1L:n.leg] - 1 + !is.null(title)) * ... : longer object length is not a multiple of shorter object length 6: In top - 0.5 * yextra - ymax - (rep.int(1L:n.legpercol, ... : longer object length is not a multiple of shorter object length 7: In xt + x.intersp * xchar : longer object length is not a multiple of shorter object length 8: In if (xc < 0) text.width <- -text.width : the condition has length > 1 and only the first element will be used 9: In if (xc < 0) text.width <- -text.width : the condition has length > 1 and only the first element will be used If I remove “bquote” from “legend,” no warnings are produced. By the way, “xc,” “yextra”, and other variable listed are not part of my script. I have no idea what to do with the warning information. Is there a better way to write my “legend” code?
